I agree with the earlier in October the better. I have ridden the Katy in mid to late October, early November, but one is always taking a chance to do so and since you have novice riders with you, why take a chance on it being cold and miserable. Also, the leaves should be turning by the first part of October; so that should make for an enjoyable and scenic adventure.
